PAGE: 2 of 6 I. Installation Please remove all shipping and crating materials carefully. Be sure to remove the plugs from the inlet and outlet openings. Dispose of all crating materials safely. After positioning the Model 4 Duplex Filter unit in its proper location, secure the adjustable tripod leg assemblies to the floor or platform. (Some installations may not require the adjustable tripod leg assemblies.) The duplex system is normally supplied with the inlet-outlet connections in a horizontal orientation (facing in opposite directions) as shown on the last page of this manual. However, the inlet-outlet orientations can be varied depending on your application. The inlet service line should be connected to the inlet flange or NPT coupling located near the top of the units (above basket level). The outlet service line should be connected to the outlet flange or NPT coupling, located near the middle or bottom of the units (below basket level). There are two 1/4" NPT ports, one on the inlet tee and one on the outlet tee, of the Model 4 Duplex Filter unit. Additionally, there is one 1/4" NPT port in each cover of the Model 4 Duplex Filter unit. These ports can remain plugged or used for pressure gauges, or special fittings as your application requires. Some installations require electrical grounding of all equipment, be sure to provide adequate grounding where necessary. After completing installation be sure to double check connections for integrity. Your Model 4 Duplex Filter unit has been factory pressure tested leak free, therefore, any seepage problems usually occur from improper installation connections. You are now ready to install the filter baskets and bags. (Your Rosedale Model 4 Duplex Filter unit consists of two Rosedale Model 4 Filter units. They are designed for continual flow through one unit while servicing the other). Remove cover by loosening the cover eyenuts on one of the filters. The eyenuts in the slotted corners should be loosened sufficiently to swing free. Loosen the third eyenut sufficiently to allow the top cover and closure assembly to swing away from the top of the unit. Place the basket into the filter housing, make sure the basket flange is firmly seated on top of the basket collar. Insert bag into the bag basket making sure filter bag ring is firmly seated on top of the basket flange. For best results, be sure filter bag is installed fully extended to the bottom of the basket. Before replacing cover assembly, inspect cover seal gasket (replacing as necessary). Close cover and alternately tighten the three clamp assemblies evenly to ensure a leak proof seal between the cover and housing body. The ft-lbs recommended torque value for 1/2"-13 closure assemblies is 30-45. Repeat the above steps for installing the filter basket and bag for the other unit. Your Rosedale Model 4 Duplex Filter unit is now ready for operation!

PAGE: 3 of 6 II. Operation Filter System Start-Up Procedure: Prior to turning on the flow to the inlet service, please make the following checks: 1. Check inside filter unit to be sure basket and filter bag (if applicable) are in housing and do not require cleaning or replacement. If necessary install a clean filter basket and bag (if applicable). 2. Check that filter unit cover is securely fastened to housing. You are now ready to open the flow to the inlet service line. Slowly open the inlet service line approximately 25% of normal operational flow (open slowly as not to displace filter bag inside the housing). After filter unit is pressurized and vented, slowly open outlet service line unit valve until completely open. Complete opening of inlet service line until desired flow rate is reached. Once the desired service flow has been established, the filter will operate efficiently until dirty. However, under no circumstances should more than 15 PSI Differential Pressure through the filter be obtained. Operating the filter unit with a high differential may cause filter bags to rupture and/or cause damage to filter system and downstream equipment. To prevent excessive drop through the filter unit, regular inspection of the filter media is required. Monitoring of differential pressure through the housing can be utilized as a means of determining whether or not the filter media needs cleaning or replacement. Filter Media Cleaning/Replacement Procedure (Side of duplex not in service): The duplex system features continuous filtering capabilities. When it becomes necessary to clean or replace filter media during continuous operating conditions, follow the procedure outlined below: 1. Open balancing valve, if applicable, to equalize pressure in both housings. 2. Unlock mechanical valve actuator assembly by removing the lynch pin. 3. Slowly move the mechanical valve actuator lever 90( to divert the flow to the clean filter vessel. 4. Replace lynch pin to prevent accidental switching of fluid flow to filter being serviced. 5. Close balancing valve, if applicable. 6. Relieve the pressure from the filter vessel being serviced. WARNING CONTENTS UNDER PRESSURE Relieve Pressure in accordance with Manufacturer s instructions before opening Filter Vessel. FAILURE TO DO SO MAY RESULT IN SERIOUS BODILY INJURY. 7. Drain housing sufficiently to access filter basket. 8. Remove cover by loosening the cover eyenuts. The eyenuts in the slotted corners should be loosened sufficiently to swing free. Loosen the third eyenut sufficiently to allow the top cover and closure assembly to swing away from the top of the unit. 9. Remove filter basket and clean thoroughly, remove the filter bag (if applicable) and throw away.

PAGE: 4 of 6 (Cleaning and reusing the filter bag is not recommended.) 10. Remove debris and sludge from inside the inlet portion of housing to avoid interference with cover seal or flow of fluid being filtered. 11. Remove basket seal (if applicable) and inspect, replace if necessary. 12. Install clean filter basket and filter bag (if applicable). Place the basket into the filter housing, make sure the basket flange is firmly seated on the basket collar. If applicable, insert bag on top of the bag basket flange making sure filter bag ring is firmly seated inside the basket flange. For best results, be sure filter bag is installed fully extended to the bottom of the basket. 13. Inspect cover gasket for cuts or other signs of failure and make sure it is properly seated. 14. Move cover back into position, and alternately tighten the three clamp assemblies evenly to ensure a leak proof seal between cover and housing body. The recommended torque value for 1/2"-13 closure assemblies is 30-45 ft-lbs. Your Rosedale Model 4 Duplex Filter unit is now ready for continuous operation during the next filter media cleaning/replacement maintenance cycle. III.
